Product Description

Features:

1. This intelligent controller, adopting function block programming, having large programming capacity, being f reely
fprogrammed according to different users and different fields, can run at your desired time table and the RTC
accuracy can reach second and makes your time control more accurate. And up to 128 time sessions can

be set , especially suitable for time-control system.

2. Safety password function makes your program absolutely safe. Before writing program, password can be set. And only
after entering the correct password, can the program be modified.
3. It is equipped with a removable, convenient and programmable LCD, providing 64 friendly human-machine interfaces,
32 virtual keys, having the function to display the alarming message and parameter and to modify the parameter.
When needed, it can be installed. And when not needed, it can be removed and replaced with an ordinary front panel.
Thus the cost will be greatly reduced.
4. The input can receive not only the digital input but also the analogue input to perform the control and . transmission of

fthe temperature, moisture, pressure, flow level unit and so on.

5. It has well-featured and compact design with 12 point input and 8 point output. Equipped with expansion module, it can
be expanded into 82 I/O better ,and to MAX 122I/O.It can be connected with telephone voice module and remote control
module to perform the notification and alarming function. And the connection between the host and the module can
be Bridge SR-CBA or flexible connection SR-ECBA.
6. The machine has short-circuit protection (internal) and relay output protection (external) function, which makes your
usage safer and easier.
